The efficient and chemoselective preparation of acetals and ketals from carbonyl compounds, transacetalization reactions, the conversion of epoxides to acetonides, and the preparation of acylals from aldehydes in the presence of catalytic amounts of 2,4,4,6-tetrabromo-2,5-cyclohexadienone (TABCO) are described.

The heterobimetallic trinuclear suffido clusters [(Cp*Ir)2(μ3-S)2MCl2] (M = Pd (3), Pt (4); Cp* = η5-C5Me5) were synthesized from the dinuclear hydrogensulfido complex [Cp*IrCl(μ
Regioselective addition of alcohols to internal 1-aryl-1-alkynes catalyzed by a triangular heterobimetallic Ir2Pd sulfido cluster

The triangular heterobimetallic sulfido cluster [(Cp*Ir)2(μ3-S)2PdCl2] prepared from [PdCl2(cod)] and [Cp*IrCl(μ-SH)2IrCp*Cl] was found to catalyze the addition of alcohols to alkynes to give the corresponding ketals. In particular, internal 1-aryl-1-alkynes were transformed into the corresponding 2,2-dialkoxy-1-arylalkanes with high regioselectivity. The analogous Ir2PtS2 cluster proved to be much less selective.
